This is a AU so it's not what actually happens in the manga/anime
and there shouldn't be any spoilers, if their is then ill warn you.
It was a known fact around the guild that, Lucy and Natsu were becoming closer, they acted more like a couple than best friends... But they always denied it, Lucy was one of the smartest guild members but she was as dense as Natsu when it came down to romance.
They seemed to joke around more, they would greet each other with hugs and laughter - Heck, Lucy actually started to allow him to have sleep overs, she even got some sleeping bags and they would have mini slumber parties. They really were dense.
They started acting like this ever since the Grand Magic Games, Cana began a betting pool, so far the grand total was 2,450,658 jewls, no one has won yet.
The change was unnoticed at first, because Lucy and Natsu had one of the closest relationship out of anyone in the guild, maybe apart from the Strauss siblings and of course, Bisca and Azlack... Not the close that Juvia and Gray had, that was more... Psychical (and mostly one sided for that matter).
Most people was surprised on how well Lisanna took it, they expected her to show... Some jealousy towards the two, she simply explained that in Edolas, her and Lucy Ashley got along well, and most of her free time would either be spent; Breaking up Lucy's and Levy's fights, Stopping Lucy from torturing poor Natsu Dragion or teasing the two about their relationship.
And along with Levy, Mira and Happy (Sometimes Juvia too) They would tease Lucy to death about her and her Natsu.
At first it was just simply gestures such as ordering each other drinks and food, and the way they would always annoy each other, but the members of the guild took it more as. Lucy and Natsu being Lucy and Natsu.
They grew a bit more suspicious as they spent more than 'usual' time together, whenever they weren't fight (Natsu only) or spending time with the girls (Lucy only) they were always together... Well apart from the weird things, for example; Getting changed and taking baths or showers.
Bets started being placed once they realised that they were always in contact, would it be sitting next to each other, a hug, walking. (Happy admitted that Lucy now allowed them to sleep in her room, in her bed - and that they would usually wake up to breakfast) Natsu would usually have his arm around Lucy's shoulders, and during missions Lucy would lay Natsu's head on her lap and stroke his hair (She claimed it help him with motion sickness, so Erza wouldn't have to knock him out or Wendy use troia).
People thought they were a couple when Lucy was sitting down with Erza and Gray when Natsu walked up and hugged her from behind, nuzzling into her neck, she never pushed him away and just continued talking to the two, earning puzzled looks from Gray and Erza, and half of the surrounding - lets just say Mira ended up in the infirmary from fainting.
Once Happy and Natsu left for fishing, a few guild members asked about their relationship, to which she replied. "What relationship? me and Natsu are just best friends, just like me and Levy, and me and Erza, it doesn't mean were dating, again were just best friends... If you were to ask me then the most likely person to be in a relationship is either Gray and Juvia or Gajeel and Levy" and with that she carried on to join Natsu and Happy with fishing.
Leaving the guild speculating and with questions, and four very red mages.
So a new bet started, who ever can get the two to confess their feelings and go out with each other, wins the all ready collected jewls, and an extra thousand from each member joining in.
With only two rules:
You need proof of them dating and how you done it.
And no shortcuts.
And that's were our story begins
here be thee prologue, the first chapter should be out today!
